I/O Error on SAN Disk
Hi,

I have a production solaris 10 SPARC system (portal). Yesterday legato/Networker gave an I/O Error on one of the files on its SAN mounted disk.
I went to that particular file on the system, did an ls and it showed the file. However, ls -l did not work and it said IO error.

What is the solution to fix this IO error. fsck?

What was the original error? is the message from 11/22 the first one logged?

unmount, fsck and remount

We saw the first error via legato. On the server, the following:
Code:
[root@plumcrt01 /opt/luminis/products/ds/slapd-cp/locks/server] # ls
1198
[root@plumcrt01 /opt/luminis/products/ds/slapd-cp/locks/server] # ls -l
./1198: I/O error
total 0

The second error via legato was an ldif data file. When we cated the file, it had garbage values at the end

Well, ran fsck it found some errors and fixed it. Everything appears to be fine, however, the cause of the IO error is still a mystery.

First Error (occurred during movement)
Code:
Nov 12 21:57:19 plumcrt01 savecore: [ID 570001 auth.error] reboot after panic: free: freeing free frag, dev:0x14800000008, blk:33717, cg:2, ino:13487, fs:/opt/luminis

my best guess is it happened when the server crashed. you should find out why the system crashed.

lol, got mail from SUN stating that it might be because I did not connect the fiber cables properly.
Any way all is good till now. I am assuming that /opt being 100% full might be the cause since, the SAN partition was mounted on /opt as /opt/luminis
